5) \(\frac{1}{2}\sqrt{196}+1,5\sqrt{0,36} = \frac{1}{2}\cdot14 + 1,5 \cdot 0,6 = 7 + 0,9 = 7,9\)
а) \(\sqrt{0,36\cdot25} = \sqrt{0,36}\cdot \sqrt{25} = 0,6 \cdot 5 = 3\)
б) \(\sqrt{24,5^2} = 24,5\)
2) \((\frac{3\sqrt{2}}{18})^2 = (\frac{\sqrt{2}}{6})^2 = \frac{2}{36} = \frac{1}{18}\)
5) \(\sqrt{0,25\cdot64} = \sqrt{0,25} \cdot \sqrt{64} = 0,5 \cdot 8 = 4\)
Ответ: 5) 7,9; а) 3; б) 24,5; 2) \(\frac{1}{18}\); 5) 4
